My experience comes from the days of film so it may or not apply. It is normal if you are willing to accept the assignment and there isn’t really any reason not to. Back in the day, we had a commercial client that wanted all of the film we generated. The assignments were a fee plus film costs and things like helicopters and we (made sure we) generated a ton. We strip developed it and gave them the rolls - the good the bad the ugly. The bigger the pile of film that happier they were. Of course each assignment was priced accordingly.
